The main function of the fuse link

The main function of the fuse link is to provide overcurrent protection within the circuit.

When the current in the circuit exceeds the rated current of the fuse, it will melt due to overheating, thereby cutting off the circuit to prevent excessive current from damaging other components within the circuit, such as wires and electrical equipment, and to avoid potential safety hazards like fires and electric shocks.

Fusible links are commonly used for circuit protection in automotive, industrial equipment, and power systems.
